Rolling a Google Service Account JWT in Node.js without the googleapis package

The googleapis npm package is the default answer for calling Google APIs from Node.js. It works, but it installs around 380KB and brings in over 450 transitive dependencies. For a single API used in a CI script — the Search Console URL Inspection API — the underlying auth flow is simple enough to handle directly. I built scripts/gsc-inspect.mjs to check index status for published URLs. It's about 60 lines, uses three Node.js built-ins ( crypto , fetch , URL ), and adds zero packages to the repo.
